Signs and Causes of Enlarged Heart

An enlarged heart, medically known as cardiomegaly, is a condition where the heart grows abnormally larger than its normal size.....Read Full Article>>

There are several causes of an enlarged heart, including the following:

1. High blood pressure.

High blood pressure is a leading cause of an enlarged heart. Over time, the constant pressure can damage the heart muscle, causing it to grow abnormally larger.

2. Coronary artery disease.

Coronary artery disease occurs when the blood vessels that supply the heart with blood become blocked or narrowed. This can lead to an enlarged heart due to the lack of oxygen and nutrients reaching the heart muscle.

3. Cardiomyopathy.

Cardiomyopathy is a disease of the heart muscle that causes it to weaken and become enlarged. This can be due to genetic factors, infections, or other underlying health conditions.

4. Heart valve problems.

The heart has four valves that control the flow of blood in and out of the heart. If these valves become damaged or don’t function properly, the heart may become enlarged as it works harder to pump blood through the body.

5. Arrhythmias.

Arrhythmias are abnormal heart rhythms that can cause the heart to work harder than usual, leading to an enlarged heart over time.

6. Other health conditions.

Enlarged heart can also be caused by other health conditions such as diabetes, obesity, and thyroid disorders.

Symptoms of an enlarged heart may vary depending on the underlying cause and the severity of the condition. However, some common symptoms include:

1. Shortness of breath: This can occur even during light physical activity or while resting.

2. Swelling: Swelling in the legs, ankles, and feet is a common symptom of an enlarged heart.

3. Fatigue: The heart has to work harder to pump blood through the body, which can cause fatigue and weakness.

4. Chest pain: Chest pain can occur when the heart is not getting enough oxygen due to reduced blood flow.

5. Irregular heartbeat: An enlarged heart can cause an irregular heartbeat, which can lead to palpitations and dizziness.

6. Fainting: In severe cases, an enlarged heart can cause fainting or loss of consciousness
